Application filed July 8, 1907. Serial No. 382,789.

To all whmn it may concern? Beit known that I, J OHN OSCAR Nnmmn, a cltlzen of the United States, residing at State of Illinois, have invented certain new and useful Improvements in Plow-Cars, of which the following is a specification.

a new and improve construction of the plow forming a part of cars used for ballasting and other purposes. As is well-known these cars are. provided with plows secured beneath the floors'of the cars and adaptedvto spread the material dumped upon the track. Owing to the severe nature of the strains and shocks to whichthese parts are subjected it is necessary that they be constructed of great strength and so formed as to encounter the least resistance possible in spreading the ballast or other material.

In the drawing Figure 1 is a side elevation of a plow constructed according to my invention, the outline of the car to which it is adapted to be attached being shown in of the plow construction.

The body of the plow consists of converging plates 1 and 2, these plates\preferably being curved in cross section, as illustrated. At their forward ends the plates 1 and 2 are outwardly deflected'forming flanges 3 and 4, saidflanges in the assembled structure being parallel to each other. Instead of securin these flanges together dglrectly, I provide For increased strength, an also secure a superior operation of the plow by passing a central plate 5 between the flanges 3 and 4. v The plate 5 lies in the axis of the plow and projects forward a considerable distance beyond the ends of the plates 1 and 2, thus forming a cutting edge whidh is adapted to readily enter the materialon the track preverging side plates 1' and 2. The center plate 5 and theside plates 1 and 2 are se cured together by means of rivets passingl through all three of said arts. The strength of the structure is great y increased by the reinforcing action of the center plate, and

this plate also relieves the side plates of the initial shock and strain during the.action of the plow upon the,material on the track.

1 The draw-bar 6 in the present instance is shown secilred directly to the center plate 5.

The construction of the car and the mechanism for raising and lowering the low may be of any preferred form and nee not be described in detail as the invention herein claimed is limited to the construction ofithe plow and its attachment to the body of the car. i a

What I claim is:

1. In acar of the class described, a plow comprising converging side plates and a center plate between said side lates 2. In a car of the class descri ed, a low comprising a center late and side p ates securedcto the sides 0 said center plate and divering therefrom.

3. In a car of the class described, a plow comprising converging side plates, parallel flanges on said plates at their adjacent ends, and a center plate between said side lates and projecting forward therefrom, sai side plates being secured to each other and to JOHN OSCAR ,NEIKIRK.
